Be it known that 1, CHARLES H. RUDGE,-.a

subject of the King of Great Britaim'residing' at 184 Warren street, Newark, inthe con nty of Essex and State of New Jersey, have invented certain new and useful Improvementsin Cropper-Dock-Formin g Machines; and I do hereby declare the following to be afulhclear, and exact description of the inventiomsuch as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying. drawings, and to letters of reference marked thereon, which form a part of this specification.

The objects of this invention are to provide for the use of harness-makers a machine for bending crupper-docks into the desired shape, to thus save the labor of doing it by hand and to secure a more uniform bending than can be done by hand, to bend the crapper-dock; Without wrinkling-the same and enable it to' be held in bent position to set or permanently assume its bent form, and tosecureother advantagesand results, some ofwhich may be referred to hereinafter'in connection with the description of the working parts. p

The invention consists in the improved ma chine for forming crupper-docks and in the arrangements and combinations of parts of the same, all substantiallyas will be hereirr after set forth, and finally embraced in the clauses of the claim. g,

Referring to" the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several views, Figure 1 is a side View of my improved machine in perspective; and Fig. 2 is a plan of the same,'the bending-levers being closed. Fig. 3 is a plan of the machine withthe bending-levers broken away. Fig. tis a side elevation of the machine with a crupper-dock therein'be'nt to itsfinal position, the bendinglever next the observer being removed to more clearly disclose the parts. Fig. 5 is a do tail view of the sliding member'and .its slideway in side elevation 5 and Fig. 6 is a section of the same on line 0:, Fig. 5, looking in the direction of the arrow.

In said drawings, a indicates'a base-plate, of either wood or metal, upon which the working parts of my machine are mounted. Near one end of the said base-plate is a fixed memberb, comprising a suitable base I), secured to the plate a and at its upper portion constituting a rest'b curved in plan and also concaved in vertical direction at its face next the farther end of the base-plate a, the said curvatures being adapted to conform to themiddle portion of a stuffed crupper-dock. Toward the said other-end of the base-plate a is a slideway formed of oppositelyrdi'sposed cleats c c,s'ecured to the base-plate and undercut at their facing edges to receive the opposite baseflanges d of a sliding member d,which member is adapted to move toward and away from 6 5 the stationary member. b, above described. Said sliding member is moved by means of a hand-screw 2, Working in a threaded nut or seat 6, secured to the'base-plate. At its extreme opposite end from the stationary mem- 7o ber 12 the end of the sliding member d next said screw is provided with an upright pro- '3' ectin g plate 612, which plate carries at its outward face a yoke 62 in which the end of the screw e is adapted to work loosely, so as to 7 5 carry the sliding member at with said screw in its longitudinal movement. A hand-wheel e attheoutwardend of the screw 6 and pro je'c'ting' beyond the base-plate 0. enables the sliding member 6 to be adj ustedwith facility. At the end of the slidingmember 01 next the stationary member I) an extension f projects firstupwardly andthen is bent, as at f toextend rearwardly and substantially in horizontal position. At its extremity said extension f carries a former g, adapted to cooperate with the upper part of the stationary member I) to grasp the crapper-dock, the said former lying at the opposite side thereof'from the stationarymember. from top to bottomat its face, as shown in Fig. 5,'a'nd is'in plan rounded to the proper curvature 'towhich it is desired to bend the crupper-dock.

In operating the machine the crapper-dock, 9 5 straight as stuffed, is laid withits middle portion against the stationary member b, and the sliding member 63 is moved toward the same until it presses firmly against the opposite 4 side. The crupper-dock is then to be bent at roe its ends around the said former g, and to effect this I provide bending-levers h it, one

Said former is concaved o" pivoted at each side of the upper concaved portion of the stationary member 1) upon a vertical pin h, whereby the two handles or levers are adapted to swing in horizontal plane. Each lever is at its inner face and adjacent to the stationary member I) concaved, as shown in Fig. 1, to form a continuation of the concaved surface of the stationary member, and in plan the levers are bent into the form which it is desired to have the crupperdock assume, as shown in Fig. 2 more particularly. I When the crupper-dock is being placed in the machine or gripped, as above described, the two levers h h are thrown wide apart, as indicated in Fig. 3; but when the crupper-dock has been firmly gripped the next step is to swing said levers h h, by means of handles 71 k at their extremities, toward one another, thus forcing the crupper-dock into bent position. During this process of bending the former g presses firmly against the inner bent surface of the crupper-dock and serves not only to give the crupper-dock proper shape, but also prevents any wrinkling of the leather at the inner side of the crupper-dock. When the two levers h h are brought close together, they may be secured by means of a double-ended catch 13, pivoted upon the projection d of the sliding member and adapted to hook at its opposite ends over the bending-levers. It is necessary to next bend the adjacent smaller ends of the crupper-dock downwardly, and to efiect this I provide beneath said ends, as they are brought together by the bending-levers, a lower clamping-platej, pivoted, as at j, to the bend of the extensions fand being toward the former g from said point of pivoting bifurcated to form lips 70, each of which is concaved and bent downwardly and outwardly. The opposite end of the lower clamping-plate j is at its upper surface provided with corrugations or teethj directed away from the former g, and

said corrugated portion of said clamping member has also a central stud or screw Z, upon which slides an upper clamping member or plate on, also having teeth or corrugations m, like the lower plate, and adapted to be forced thereagainst by a finger-nut n on the screw l. The said clamping-plates are normally held apart by a spiral spring 0 between, so that the smaller ends of the crupper-dock can be pushed therebe-tween. Then the screw n is tightened, and the clampingplates m j are forced tightly together, so that they firmly grasp the said ends of the crupper-dock. Preferably the end of the upper clamping-plate m is slotted or perforated to slide upon a vertical guide j projecting from the lower clamping member, whereby its ac tion is steadied.

In the lower portion of the extension f of the sliding member is j ournaled a transverse shaft q, projecting beyond said extension at its opposite ends. The said extension is at that portion preferably slotted or cut away from its middle part'to expose the said shaft and afford space for an arm q, fixed upon said shaft. Said arm projects outwardly from said extension f beneath the toothed or corrugated end of the clamping-plate j and is pivotally connected thereto by means of a link 0", while the outward end of the shaft q carries a handle or lever s, by means of which the said shaft can be oscillated to tip the forward end of the clamping-platej downward to its normal position. Thus in the operation of the machine after the smaller extremities of the crupper-dock have been brought to their adjacent positions by means of the bending-levers h h they are firmly clamped by the plates mj, just described, and then the said clamping means or plates are tilted upon the pivotj by means of the shaft q and its handle 3. This carries the extremities of the crupper-dock downward, and back from said extremities bends the end portions of the crupper-dock over the rounded lips 70, which serve as formers. When the parts are brought into this position, as shown in Fig. 4, the shaft q is locked, preferably by means of a ratchet-wheel 75, fast on said shaft at its end opposite the handle .5 and adapted to be engaged by a pawl t, pivoted upon the ex tensionfof the sliding member. The crup per-dock p is then left to set, while another one is stuffed and gotten ready for bending.

By the device thus described it will be seen that I provide means for very easily and quicklybending the crupper-docks, and, furthermore, without any possibility of wrinkling at the inside of the bend. Again, it will be obvious that all crupper-docks will be bent uniformly and to the same extent, thereby securing a neater appearance and a better fit on the horse.

Having thus described the invention, what I claim as new is 1. A machine for bending crupper-docks, comprising a stationary member I), concaved in plan and adapted to fit against one side of the crupper-dock, a sliding member convexly curved in plan, and adapted to lie against the other side of the crupper-dock, means for forcing said sliding member toward the sta-- tionary member to grip a crupper-dock, and bendinglevers pivoted at opposite ends of said stationary member to swing in horizon the combination of two curved clamping members adjustable in relation to each other, the one at the inner ends of the curve being extended rearwardly at its ends to constitute a former around which the crupper-dock may be bent, bending-levers pivoted at the ends of the outer clamping members adapted to swing in horizontal plane, and tilting gripping means adapted to grasp the ends of the erupper-dock, when brought together by the said clamping-levers pivoted to opposite ends of said clamping member and adapted to close around the former to press the crupper-dock thereagainst.

5. Inamachine forbending crupper-docks, the combination of a former shaped in plan to give proper form to a crupper-dock and being vertically concaved at its edges to receive the crapper-dock, of curved bending-levers adapted to swing in the plane of the said former and close therearound and a supporting member to which said bending-levers are pivoted.

6. The combination with the stationary member 17, and bending-levers pivoted thereto, of a member d, adapted to slide toward and away from said stationary member and providing a former, and a screw for i'noving said sliding member.

7. The combinationwith the gripping memhers I), d, one comprising a former around which a crupper-dock may be bent, and bending-levers, of pivotal clamping-plates adapted to grasp the ends of the crupper-dock when brought together one of said plates providing a curved surface next to the crapper-dock and means for tilting said clamping-plates.

8. The combination with the gripping members b, d, one comprising a former around which the crapper-dock may be bent, of a piv otal plate at the rear of said former presenting a curved surface adapted to lie at one side of the plane of said bending, means for clamping the ends of the crapper-dock to said pivoted plate andmeans for tilting said plate and clamping means.

9. The combination of members b, d, adapt ed to grip a crapper-dock at its middle one of said members, constituting a former, bending-levers pivoted clamping means adapted to grasp the ends of the orupper-dock when bent, curved lips onsaid clamping means adapted to lie at one side of the plane of the crupper-dock, and means for tilting said pivoted clamping means, whereby the ends of the crupper-dock may be bent over the said curved lips.

In testimony that I claim the foregoing I have hereunto set my hand this 16th day of January, 1902.
